Low-concentration electrolytes (LCEs) offer a cost-effective and sustainable route toward practical lithium metal batteries (LMBs), yet their solvent-governed solvation and interfacial chemistry often result in unstable lithium deposition behavior. Herein, we uncover the decisive role of solvent molecular structure i...
Lithium metal batteries (LMBs) require electrolytes that stabilize both lithium metal anodes (LMAs) and cathodes. Conventional strategies mainly reconstruct bulk solvation structures, often perturbing the intrinsic properties of the electrolyte. Here, we introduce an ion-regulated strategy to selectively tailor inter...

Ether electrolytes in Li‐metal batteries are severely constrained by parasitic anodic oxidation and solvent ring‐opening polymerization (ROP). To overcome this, we propose an “anchor‐and‐shield” strategy using 0.05 M TBABH4 in 1 M LiFSI DME/DOL. Nucleophilic BH4− incorporates into the Li+ solvation shell, neutralizing...
